These models were for sale on a site and I was wondering if anyone could help me identify what these models actually are before I decided to buy them.
Looks like two Space Marine Commander. That box can be used as either a Captain or a Lieutenant.
This box set contains one multi-part plastic Space Marine Commander, including nine different weapon options, three variant heads and additional parts to further customise your model.
Left is a Captain with a combi-plasma and a power fist; Right is a Lieutenant with two power swords.
